In general, resources must be activated before they can be accessed by the driver so that the bus driver can map the resource into the devices space. .Pp Its arguments are as follows: .Bl -item .It .Fa dev is the device that requests ownership of the resource. Before allocation, the resource is owned by the parent bus. .It .Fa type is the type of resource you want to allocate. It is one of: .Bl -tag -width SYS_RES_MEMORY .It Dv SYS_RES_IRQ for IRQs .It Dv SYS_RES_DRQ for ISA DMA lines .It Dv SYS_RES_IOPORT for I/O ports .It Dv SYS_RES_MEMORY for I/O memory .El .It .Fa rid points to a bus specific handle that identifies the resource being allocated. .It .Fa r points to the .Ft struct resource returned by .Xr bus_alloc_resource 9 . .El .Sh RETURN VALUES Zero indicates success.
